@ne object ot my invention is to provide a heater which may be readily and conveniently ep lied to the exhaust pipe ot a motor vehicle or delivering heated air into the t body of the car at a plurality of places, as tor instance in advance oi the front and rear seat, respectively, without employing more than one heater for each car, thereby reducing the cost ot the heater equipment per car, yet 'HD obtaining es much if not more heat than With two heaters as would be required for a similar installation using heaters as heretofore made. Another object of my invention is to provide e. heater assembly by which drafts or l@ currents of heated air are blown or forced into the cer, thereby obtaining a large volume cit heated air for the car.

el further object of my invention is to pro vide liee means in the heater casing for 2@ increasing the length of travel or the air herethrough and thus entciently heat the oir tor czar Warming purposes Without r that the lie-eter be oit undue dimensions still further object of my invention is 'to provide a heater assembly simple, yet eihcient in its construction, and which may be applied to en exhaust pipe Without cutting the latter in two, thereby facilitating the applit@ cation oi the heat r to the pipe,

ALl.nottner object my invention is to pron vide e construction which may t exhaust pipes ott dido-rent diemeters as found in ditlerent oi cars thereby enabling the heater proper to he ci" one size 'for ell pipes The invention consists iirther in the matters hereinetter described and claimed.

l indicates the engine; 2, the exhaust pipe extending from the engine toward the rear of the car under the door 3 thereof; and 4, 4 indicate the front and rear seat in the body 5.

The heater assembly ot my invention is applied to the exhaust pipe 2 beneath the body 5, preferably under the front seat l, as shown in Fig. 1. The heater comprises a conduit 6, preferably lll-shape and disposed to have both its legs o ening into the exhaust pipe. Said condult 6 is applied to one side of the pipe 2 and extends horizontally outward therefrom beneath the body. The legs oi the conduit 6 are connected with and open through a base block 7, which ts in a rectangular opening 2 provided in the Wall of the exhaust pipe, Without cutting the latter in two, es shown in Figs. d and 5i. The block 7 has outwardly projecting lugs or ears 7a? 7a on the opposite sides thereof, to which are bolted bands 7b, 7 applied tothe pipe il on the side opposite the block iter clemping the same thereto., The conduit 6 and block 7 are preferably cast in one piece so es to cheapen the cost of construction and evoid joints through `which exhaust gases may leali.,

The block 7 carries a deector, preierebly in the 'torin of e disc d disposed in the pipe 2 between. the legs of 'the conduit, as shown in Fig. 5. 'ilie disc 8 hes e 9 rotetebly supported in the block 7 between the legs of the conduit, eo that the disc may be turned into and out oi position extending acr the pipe 2. for deilecting exhaust gases "troni the pipe it into end through the conduit "3, as indicated in dotted lines in Fig. llor turning the disc or valve 87 the stero Q hes erro in its outer end rfi/til en ing rod or Wire 1l connected thereto.

'Z are turned inward to ontiv'erdly pro jectin ribs or 'webs l? on the blocs. to close Le casing et the hilocirg shown For supplying air to the casing 12, I provide an intake pipe 18 extending to the front of the car and having a funnel-shaped or flared inlet end 19' just behind the radiator fan 20, so that air will be blown into and through the heater casing 12, as shown in Fig. 1. This pipe 18 opens into the casing 12 adjacent the block 7 so as to deliver air at the hottest part of the conduit 6. To the opposite end of the casing 12, I attach two pipes or conduits 21, 21, one leading to the floorof the car in advance of the iront seat 4, and the other to the floor of the car in advance of the rear seat 4, as shown in Fie. 1.

rranged in the casing 12 are a plurality of bathe plates 22, 22. These are disposed to extend across the casing between the top and bottom walls thereof. The plates are divided into upper and lower portions cast integral with the respective sections of the casing, as shown in llig. 1i. The upper portions of the baiiles abut against the lower portions of the corresponding baffles, as shown in said figure. Each baiiie extends across the casino from one side and terminates short of the other side to provide an opening 23 about such end of the baiiie. These. openings alternate so as toiincrease the'l length of travel of the air through the casing..

The conduit d, as shown in Fig. 7, is nrovided on the inside with a plurality o. inwardly projecting baes 2a to malie a turbulent flow of exhaust gases through. the conduit and thus 'turn all portions of the heated gases against the metal of the conduit to eis edectively heat the same.

.fit the place where each outlet pine 21, 2l, discharges heated air into the body of the ear through the door 3, l provide the assembly shown in detail in Fig. l(i. At each of these places, l provide a pipe fitting 25 secured to the floor of the car by bolts 26, 26 and having Within it a damper in the form of a dise 27 mounted on the stern 28 having an. arzn 29, to which is connected a pull rod 30 extending up through the door of the car, as shown in Figs. 1 and ti. The conduit 21 .is coupled to the lower end of the .tting 25, and the upper end of the latter where it opens through the licor-boards is covered by a cowl 31 held in place by the bolts 26. This cowl has its marginal portions extending downward so as to space its body portion above the open end ot the fitting 25, and has a. series of marginal openings 32 to permit the outiiow of heated air from the assembly.

Gaskets 33, 33 are interposed between the side margins of the block 7 and the outer wall of the exhaust pipe 2, so as to provide tight joints along such. parts when the block is tightly clamped against the exhaust pipe (F ig. To provide joints at the opposite ends or the block '.7, l provide end plates 34, 34. These are secured to the ends of the block by screws 35, and the inner edges of the plates are curved to conform to the outside curvature of the exhaust pipe 2, as shown in Fig. 8. To accommodate the heater assembly to exhaust pipes of different diameters, as used in different makes of cars, I employ end plates 34 having their inner edges formed on diiferent radii, so that there will be a set of plates to conform to the currature of the different pipes' and thus permit the heater assembly to be made standard for all sizes of exhaust pipes.

lVith my invention, only one heater is required to supply heat to two or more places in the car body. This is an i1npor tant factor of my invention because it reduces the cost of heater installation per car, and does the work of separate heaters, one at each place where heat is required, as with heaters as heretofore made. Moreover, with my invention heated air is blown or forced into the car body, thereby giving a large volume ot heated air for the car. The heater of my invention is simple in construction is easily applied to an exhaust pipe, and is eilicient as a car warmer.

The structure shown and described may loe variously changed and modified without departing from the spirit and scope of my invention.

A heater having a substantially il shaped conduit to he attached to an exhaust of a motor vehicle, a casing enclosing, said conduit and having an air intake and an outlet, bao plates extending across the casing between the same and said conduit, said casing and plates being divided into upper and lower sections with the sections oi the plates cast integral with the corresponding sections oi the casing, and lugs cast en 'the legs ot the conduit to which the casing sections are attached.
